Re: Fuel

a little bit of what? hesitation?

run some seafoam through the motor, then change out plugs and filters(oil, fuel, air).

automatic? could be tranny hesitation(4r70w normal sucky behavior)

Re: Fuel

hrm, definately change out the plugs after a seafoam. 98's have plug wires correct(as 99+ get Coil on Plug), so id check those as well.

ive always found stumble/hesitation to be caused by igntion/timing, rather than a fuel problem.

Re: Fuel

fuel filter, plugs, plug wires, inspect coil packs. That might make all the difference. Start small and work your way to the harder more expensive items but DEFINATLY change the fuel filter EVERY year.

Re: Fuel

I would go with changin the fuel filter, spark plugs. I know in my 2000 ford F-150 4.2l v6 i change my fuel filter every 15000 miles and it has 142000miles with a lot of upgrades and no problems.
